The Mathey Dearman Chain Clamp is not intended to support or lift the entire length of the pipe.

Never use the chain clamp as a ground for a plasma or welding systems

Always check the chain clamp for defects such as arc marks, abrasions and nicks prior to operation.

Make sure that the chain clamp will function properly prior to attempting the alignment or reforming of pipes or fittings.

The chain clamp should never be used as the sole support of the pipe or fitting.

When using the Chain Clamp, basic safety precautions must always be followed to reduce the risk of personal injury.

Always operate the Chain Clamp in accordance with the operating instructions.

The pipe must be secured to the table or pipe stand, prior to mounting the machine on the pipe.

Reforming and Alignment capacity will vary depending on pipe diameter, wall thickness, and pipe tensile strength. If in doubt contact Mathey Dearman Inc. at (800) 725-7311.

Make sure the Main Block and the Jackbars are in full contact with the pipe before aligning or reforming the pipe.

The Level and Support Device should never be used as the sole support of the pipe, fitting or valve.

Make sure the Chain Clamp is in full contact with the mating pipe, fitting or valve.

Use only the wrench provided with the clamp.

Never use a cheater bar with the supplied wrench.

Never use the clamp as a ground connection.

Always inspect the Chain Clamp prior to use.

The mating pipe, fitting or valve should not have a taper surface of more than 5 degrees at the point where the pad of the Jackscrew will contact the pipe.

2.0 – GENERAL DISCRIPTION

The Mathey Dearman Chain Clamp is versatile: Each clamp can be used to fit-up pipes, elbows, tees, and weld-on valves,

and is useful in many other pipefitting situations. Mathey Dearman Chain Clamps are available in Light Duty and Standard

models.

These instructions are essential to understanding how to use the Mathey Dearman Chain Clamp. If you have any questions

about setting up the clamp or an application that the clamp is to perform, contact Mathey Dearman Inc. at (800) 725-7311.

We’ll be glad to help.

Single Jackscrew Chain Clamp - Aligns and forms out-of-round mating

pipe up to Schedule 40 wall thickness. If reforming is not required, a wall

thickness greater than Schedule 40 can be aligned, NOTE: The required

distance between the pipe and the bottom of the raised portion of the jackscrew

is less than the Double Jackscrew Chain Clamp and Universal Chain Clamp.

This makes it a little more difficult if you are running your root pass with a Mig

or Tig torch.

Dearman Lite Single Jackscrew Chain Clamp – Manufactured

from the same type and quality of material as the standard Dearman Single

Jackscrew Chain Clamp. The Dearman Lite Single Jackscrew Chain Clamp will

typically align pipe up to Schedule 40 wall thickness. The Dearman Lite Clamp

is capable of some limited reforming tasks (see Chart 1 for details).

Double Jackscrew Chain Clamp - Aligns and reforms out-of-round

between the mating pipe and fit-up pipe up to Schedule 40 wall thickness. This

model is recommended for use where a large amount of “Hi-Lo” exists. When

no reforming is required of the mating pipe or fit-up pipe, a wall thickness

thicker than Schedule 40 can be aligned. This is an excellent clamp to use

where full circle welding is required.

Dearman Lite Double Jackscrew Chain Clamp - can align pipe up

to Schedule 40 wall thickness. The Dearman Lite Clamp is also capable of

some reforming tasks (see Chart 1).

5 of 35

Universal Chain Clamp - The “Sliding Jackbar” design of the Universal

Chain Clamp allows the Jackscrew to be positioned on either side of the weld.

This allows 100% welding and grinding without removal of the clamp. The

clamp is ideal for the alignment and reforming of pipes, elbows, tees, and

mitered joints – up to Schedule 40 pipe. It is capable of aligning pipe to

Schedule 80 if reforming is not required.

Mini-Fit - is used for fitting-up and aligning small diameter pipe. Its

lightweight and simple design makes the Mini-Fit ideal for light duty

applications, where “out-of-round” problems do not exist. The Mini-Fit is

excellent for use on conduit, copper pipe, and thin wall pipe or tubing.
